This book was released on 2016 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current earthquake-resistant design has been strongly shaped by the capacity design concept, i.e. plastic hinge development at pre-defined structural locations is permitted. However, major earthquakes, e.g. the 2010/2011 Canterbury earthquakes, demonstrated that the repair cost of damaged structures and economic losses due to downtime can be immense. Hence, in recent years the philosophy of ‘low-damage’ design has emerged. This can be achieved by allowing the structure to uplift, i.e. part of the footing is permitted to temporarily separate from the support. This work aims to understand the seismic response of upliftable structures. To investigate the structure-footing-soil interaction, rigid and laminar boxes were constructed for shake table experiments. At the early stage of the research a rigid box was used. With the development of the research a small box of 0.8 m × 0.8 m × 0.7 m and then later a large laminar box of 2m×2m×2m were developed. Shake table tests on single degree-of-freedom (SDOF) models on sand demonstrate that allowing structures to uplift can reduce bending moments and thus the development of plastic hinge. These laminar boxes are the first to have been constructed and used in the Southern Hemisphere. The results showed that the spectrum values of accelerations on the model footing are smaller than those of the free-field dry sand surface. When calculating the response of the model a significant improvement of accuracy was only achieved using the footing acceleration. A novel approach for correctly simulating model structures in one-g environment was developed and substantiated in experiments. Two multi-storey upliftable models were constructed based on both the proposed and conventional approaches. For the first time with the proposed approach key characteristics of upliftable structures, e.g. nonlinear rocking period, can be correctly incorporated in the physical experiments. Using the proposed approach, a numerical equation is derived for calculating the amplitude-dependent rocking period of structures during uplift. The period obtained leads to more accurate estimate of the maximum deformation of upliftable structures. If uplift occurs, the horizontal displacement of a structure can become larger. To control the uplift and thus the structural response, while at the same time still avoiding plastic hinge development in the structure, the weight of the footing needs to be properly determined.
Book Synopsis Seismic Performance of Soil-Foundation-Structure Systems by : Nawawi Chouw
Download or read book Seismic Performance of Soil-Foundation-Structure Systems written by Nawawi Chouw and published by CRC Press. This book was released on 2017-08-25 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic Performance of Soil-Foundation-Structure Systems presents invited papers presented at the international workshop (University of Auckland, New Zealand, 21-22 November 2016). This international workshop brought together outstanding work in earthquake engineering that embraces a holistic consideration of soilfoundation-structure systems. For example, the diversity of papers in this volume is represented by contributions from the fields of shallow foundation in liquefiable soil, spatially distributed lifelines, bridges, clustered structures (see photo on front cover), sea floor seismic motion, multi-axial ground excitation, deep foundations, soil-foundation-structurefluid interaction, liquefaction-induced settlement and uplift with SFSI. A fundamental knowledge gap is manifested by the isolated manner geotechnical and structural engineers work. A holistic consideration of soil-foundation-structures systems is only possible if civil engineers work collaboratively to the mutual benefit of all disciplines. Another gap occurs by the retarded application of up-to-date research findings in engineering design practices. Seismic Performance of Soil-Foundation-Structure Systems is the outcome from the recognized need to close this gap, since it has been observed that a considerable delay exists between published research findings and application of the principles revealed by the research. Seismic Performance of Soil-Foundation-Structure Systems will be helpful in developing more understanding of the complex nature of responses these systems present under strong earthquakes, and will assist engineers in closing the gaps identified above.

This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the last couple of decades it has been recognized that the foundation material on which a structure is constructed may interact dynamically with the structure during its response to dynamic excitation to the extent that the stresses and deflections in the system are modified from the values that would have been developed if it had been on a rigid foundation. This phenomenon is examined in detail in the book. The basic solutions are examined in time and frequency domains and finite element and boundary element solutions compared. Experimental investigations aimed at correlation and verification with theory are described in detail. A wide variety of SSI problems may be formulated and solved approximately using simplified models in lieu of rigorous procedures; the book gives a good overview of these methods. A feature which often lacks in other texts on the subject is the way in which dynamic behavior of soil can be modeled. Two contributors have addressed this problem from the computational and physical characterization viewpoints. The book illustrates practical areas with the analysis of tunnel linings and stiffness and damping of pile groups. Finally, design code provisions and derivation of design input motions complete this thorough overview of SSI in conventional engineering practice. Taken in its entirety the book, authored by fifteen well known experts, gives an in-depth review of soil-structure interaction across a broad spectrum of aspects usually not covered in a single volume. It should be a readily useable reference for the research worker as well as the advance level practitioner. (abstract) This book treats the dynamic soil-structure interaction phenomenon across a broad spectrum of aspects ranging from basic theory, simplified and rigorous solution techniques and their comparisons as well as successes in predicting experimentally recorded measurements. Dynamic soil behavior and practical problems are given thorough coverage. It is intended to serve both as a readily understandable reference work for the researcher and the advanced-level practitioner.

Book Synopsis Soil Dynamics and Foundation Modeling by : MICHAEL MAX. BUHLER

Available in PDF, EPUB and Kindle. Book excerpt: The interaction of soil with structures built in and on the ground is an important field in geotechnical engineering. Its investigation represents a demanding task for the engineer. In the scope of two interdisciplinary research projects in cooperation with a team of international scientists, we investigated experimentally and numerically the behaviour of piles and pile foundations during strong earthquakes. For decades the evolution of soil mechanics was rather separate in statics and dynamics, in particular for the interaction of ground and structure. Even now the latter is often captured in calculations by simplifying assumptions which where never verified, more so in soil dynamics than in statics. Based on the present work this is no more necessary, this can be verified by interested readers up to details. At the end of this publication it is also shown that this new state of knowledge has certainly consequences for design and construction methods.

Download or read book EFFECTS OF SOIL STRUCTURE INTERACTION AND BASE ISOLATED SYSTEMS ON SEISMIC PERFORMANCE OF FOUNDATION SOILS. written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis primarily structural induced liquefaction potential was aimed to be analyzed. Also the effect of base isolation systems both on structural performance and liquefaction potential was studied. FLAC software was chosen for the analyses so that structure and soil could be modeled together. By these means the soil structure interaction effects were also examined. Four different structures and three different sites were analyzed under two different input motions. All the structures were also analyzed as base isolated. It was mainly found that depending on the structural type and for a certain depth the liquefaction potential could be higher under the structure than the one in the free field. Also it was concluded that base isolation systems were very effective for decreasing the story drifts, shear forces in the structure and liquefaction potential in the soil. It was also found that the interaction took place between structure, soil and input motions.
